Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727128, here are decompositions:

19 + 8727109 = 8727128
37 + 8727091 = 8727128
61 + 8727067 = 8727128
79 + 8727049 = 8727128
97 + 8727031 = 8727128
139 + 8726989 = 8727128
211 + 8726917 = 8727128
367 + 8726761 = 8727128

Showing the first eight; more decompositions exist.
